Hi,
I´m interested in get a menu style like the volt page (The inline left menu in preview volt page http://www.primefaces.org/volt/ ). Could you please tell me which is the type of menu used on the page and the volt style class applied?

It is not a primefaces component. We've created a custom menu for layout by extending BaseMenuRenderer.java. Therefore, you can not use this menu in page like a primefaces component. You can only use it at left position of layout.
